The libcamera hex string adaptor specifies and casts each type
specifically to map the size of each type.
This needlessly repeats itself for each type and further more has a bug
with signed integer extension which causes values such as 0x80 to be
printed as 0xffffffffffffff80 instead.
Remove the template specialisations for each type, and unify with a
single templated constructor of the struct hex trait.
